[Early mother-infant interaction and factors negatively affecting parenting]

The social information-processing model contributes to identifying the psychological processes underlying the construct "sensitivity" in early mother-child interaction. Negative emotional states associated with inadequate self-regulation in coping with stressors affect the mother's attention skills and the processing of the baby's signals. This leads to less synchronous parental practices, particularly unsatisfactory when the baby is unhappy, or crying because the required self-regulation is not provided. This micro-social research studies the sequential profile of maternal reactions to the baby's positive/neutral vs. difficult behaviours and compares them in two groups of dyads, one with mothers who reported high levels of distress and other negative factors for parenting and another group with low levels. The unfavourable circumstances of the high stress group and their negative effects on interaction were observed in some indiscriminate maternal responses and particularly as they reacted to their baby's difficult behaviour, when the mother's regulatory role is more necessary.
